CHARLES CLARENI, OF NEIN YORK, N. Y.

WROUGHT-NAIL MACHINE.

Specication of Letters Patent No. 24,616, dated July 5, 1859.

To all whom 'it may concern.'

Be it known t-hat I, CHARLES CLARENI, of the city, county, and State of New York, have invented a new and useful Mode of Making Trought- Iron and other Metal Nails by Machinery; and I do hereby describe and ascertain my said invention, referring to the accompanying drawings, in which- Figure l, is a top plan of the machine. Fig. 2, is a side elevation.

Like parts are designated by like letters in both figures.

My improvement consists in the construction and arrangement of certain machinery by which I manufacture wrought nails of various forms, cheaply and with rapidity.

The construction is as follows: I prepare a solid and sufficient frame work a, a, consisting of a base and standards, or upright-s, in t-wo of which the main shaft b, is hung. This main shaft L, has a cylindrical cam at its center portion between the bearings, in the periphery of which there are two irregular grooves c, c', for the purpose ofgiving motion to side hammers (hereafter described). Between this center' cam and the bearings are sunk cranks or their equivalents. One of these cranks CZ, is connected with an arm c', on a shaft c, that serves as the fulcrum of a top hammer, (also to be described) by means of a connecting rod d. In front of the main shaftb, there are two other standards supporting a stout shaft that sustains a vibrating anvil f, said anvil being vibrated by means of the sunk crank f2, coupled therewith by the connecting rod f. It will be noticed that the anvil f will by this arrangement, be carried into two different eXtreme portions at each revolution of the crank and while passing the dead centers, will remain practically in a state of rest, at which time the blows of the hammers are given.

The top-hannner g, is loose on its fulcrum or shaft e, and beside it an arm projects out at e2, on the side of which are two jaws near the outer end that embrace the shank of the hammer g, as clearly represented in the iigures. These jaws do not embrace the hammer tight, but leave a space so as not to transmit the shock of the blow to the shaft c. The top hammer strikes upon the flat part f3 of the anvil in which is sunk grooves to receive the nail rods. After this blow is struck, the top hammer is raised and the anvil vibrated forward so as to bring the part f4, into the previous position of On this part of f4 there is a projection which passes between the nail rods and has a face on each side. Then this has come into place the two side hammers are brought up and strike a horizontal blow against the side of the projection f4. These side hammers li, are each pivoted on an upright shaft z', the arm of the hammer being keyed tight thereto. The journal bearings of these shafts are adjustable so as to be raised and lowered by which means new surfaces of the hammers are brought to bear upon the nail rod as it wears. By this arrangement the hammers are made to wear a greater length of time. Qn this shaft there is a sleeve c, having on its lower end an arm that works into the groove c on the cam of the main shaft l), heretofore described, by which it is vibrated horizontally. On the upper end of the sleeve 7c, there is another arm with jaws, similar to that on the shaft e, lettered 102, which actuates the horizontal hammer it, and gives the side blow. The nail rod is fed at a', by hand, regulated by a gage, or it may be automatically fed forward so as to project over the anvil as at m, and it then receives alternating blows on opposite sides until the nail is formed and ready to be cut off. This last operation is performed by the following apparatus. The standard a, just in front of the vibrating anvil has a permanent rest through which thefeed slide m, of the nail rod moves, and a projection n, from standard fn., furnishes an additional support a2, for said slide. This projection is hollow and a shaft. 0, having a crank on its outer end, moves through it, and on the inner end of the shaft there is a forked arm at o', that embraces a connecting rod p. The rod p, is attached at one end to a wrist on an arm that projects down from a bent shaft that forms the center of motion of a cutter. zf, the front edge of which curves up so as to cut off the nail as it rises. The rod p, has the hook catch, like that of a valve motion in steam engines, as clearly seen in Fig. 2, at g, and when it is raised by the crank on the shaft o, actuated by the hand of the operator, it catches on a stud on the anvil at Q, and at the next vibration of the anvil the cutter is raised and the nail cut off.

It is obvious that modifications of this simple machine may be made for special purposes, and other well known equivalents 2 i i 4,e16

A be Wrought.

Having thus fully described my invention for making Wrought nails, what I claim therein as new and for which I desire Letters Patent is,

l. The combination of the top and side hammers and vibratory anvil., substantially as herein described, so as to form two or' more nails at a time Without turning the rod, as above specified.

2. I also claim the apparatus for Connecting the driving Shaft with the top hammer, by which it receives its motion in a proper manner, as r:'peeified.

3. I also claim the connections of the side hammers with the driving shaft to produce the requisite motions thereof, and allow said hammers to be raised and lowered, as and for the purposes set forth.

l.. I also Wclaim the arrangement and operation of the cutter as described, for severing the nail from the rod. Y v
